A tape standby section that stops the tape and temporarily waits the tape until it resumes feeding, and a tape standby section that sucks and holds the tape fed a predetermined length from the tape standby section and presses it against the object to paste the tape. a tape holding section; a tape supporting section that is located at the bottom of the tape holding section and supports the tape fed from the tape standby section and retreats from the bottom of the tape holding section when pasting the tape; and a tape that has been pulled out to a predetermined length. It is characterized by being provided with a cutting part for cutting.

<Function> In the automatic tape applicator of the present invention, first, the tape is fed from the tape supply section, and when the fed tape passes through the tape standby section, it is inserted between the tape holding section and the tape support section, and the tape is fed to a predetermined length. When only 1 is sent, sending is stopped. Next, the tape is held by suction in the tape holding section, and at the same time, the tape is cut in the cutting section, and the tape on the downstream side of the cutting position is temporarily held in the tape waiting section until feeding is resumed next time. In addition, the tape support part retreats from the lower part of the tape support part, and immediately after that, the tape holding part descends, and the tape upstream of the cutting position, which is suction-held by the tape holding part, is filled with the envelope to be sealed and the contents.

A slide plate 42 is slidably disposed between the slide plates 43 and 43, and the flange 44 is also screwed and fixed to the upper part of the slide plate 42. Guide plates 43 and 43 and the slide plate 42 are attached to the lower part of the slide plate 42. It is screwed and fixed to a cover member 46 in which a cover vacuum hole 45 is bored. The lower end of the covering member 46 is covered with a tape rad 47. A position detection sensor 50 made of fiber is provided downstream of the tape radiator 47, and issues a detection signal when the leading edge of the tape reaches the lower part of the position detection sensor 50. Further, the lower side of the tape head 47 has a cavity 48, and when the tape head 47 is placed on the covering member 46, the vacuum hole 4
5 is exposed. However, when in use, it is covered with a buffer member 49 made of urethane material or the like with holes provided at positions corresponding to the vacuum holes 45 . This buffer member 49 functions to apply uniform pressure to the tape 70 when pasting the tape.

That is, the driving force from the air cylinder 41 is transmitted to the tape head 47 via the flange 44, the slide plate 42, and the cover plate 46, allowing the rad 47 to slide vertically onto the tape. Note that if the tape head 47 is slightly tapered 471 at the lower end on the upstream side, it will be easier to guide the tape to the lower side of the tape head 47 when the tape is fed.
